If you've been on social media lately, chances are you've heard about endocrine disruptors. People say they can interfere with your hormones, leading to serious health conditions. There are over 1,000 types of these chemicals, according to some estimates, and we are exposed to them daily: They can be found everywhere from your nonstick pan and canned foods to your shampoo and hair dye. The endocrine system consists of glands that secrete hormones, like estrogen, testosterone and cortisol, that then interact with targets (receptors) in the body to regulate our growth, development, reproduction, metabolism, energy balance and body weight. Chemicals that interfere with this complex communication system are called endocrine disruptors. These chemicals work in a variety of ways, including overstimulating receptors, blocking receptors so that normal hormones can't interact with them and altering hormone production or availability. Bisphenol A (BPA) is a chemical used in the production of polycarbonate plastics and epoxy resins. It belongs to the larger class of chemicals called bisphenols. The primary exposure for most people is through their diet: BPAs can leach into food or drinks from the protective, internal epoxy resin coatings of canned foods and from consumer products such as polycarbonate tableware, food storage containers and water bottles. Laboratory experiments ... have found that BPAs may cause cancer cell growth.
